TPLink WN725N does not work with OSMC

Help and Support Raspberry Pi
1

Hi,

I have Raspberry Pi 2 Model B with the wireless dongle TPLink WN725N V2.
The version of OSMC is:
osmc@osmc:~$ grep VERSION_ID /etc/os-release
VERSION_ID=“2016.01-2”

with linux kernel 4.4.1-1-osmc

I experience drop of connection as already reported here:

Initially I start installing some other drivers published by MrEngma on Raspberry forum:
https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=29752&sid=828a2c76de7ddba6867e3a8ad7f3994a&start=225

With the help of MrEngma I was able to recover the original driver in:
/lib/modules/4.4.1-1-osmc/kernel/drivers/staging/rtl8188eu/r8188eu.ko

It worked for few hours then it dropped again.It is very unstable. When I plud the device I see this in dmesg;
[ 1203.375009] usb 1-1.2: Manufacturer: Realtek
[ 1203.375026] usb 1-1.2: SerialNumber: 00E04C0001

[ 1204.217677] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

Is there any update on this driver? Is there a new version?
If this wireless dongle is so unstable can you suggest me a good wireless dongle that works perfectly with Raspberry and OSMC?
Thanks

Connection just dropped right now. Here what I see in my dmesg:
[ 1341.859464] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

As requested in the other thread after drop of connection I did:
sudo journalctl >journal.log
paste-log journal.log

So you need to provide the resulting URL here.

Have you enabled max_usb_current in config.txt? Or is dongle connected by powered hub?

6

Yes I have. Yesterday.
Dongle is connected to Raspberry. I have also an IDC Receiver attached to another USB port. Raspery is powered with a Samsung 5V 2A adapter.
As reported in this other thread, two days ago once I was able to have a wireless connection working correctly I tried to do a step further: add and external HDD.

A friend of mine borrowed me an external HDD 3.0 and I tried to connect it to Raspberry but everything frozen in Kodi. Red led was blinking. So I disconnected HDD and Kodi worked again. So I decided to set max_usb_current=1 in config.txt? But it didn’t work.

Do I have to revome this configuration? If so, why?

You need a powered hub. 2A is likely not enough power to run the pi and all the peripherals you are trying to connect.

Can you suggest me a good Power HUB to buy considering that I need to attach IRC, Wireless Dongle and External HDD. Do I need a 3A Power Supply? Can you share me a schema on how to connect cables?
Thanks

The in-tree drivers for 8188eu don’t seem very good. I do have plans to replace them with an out-of-tree driver.

This dongle works well:

https://store.osmc.tv/product/802-11n-wifi-dongle/

This is the official Pi PSU:

You can also get RTL8192CU, RTL8818CUS based 802.11n WiFi dongles and these will work with good driver support.

What about official WIPI
http://www.amazon.it/WiFi-adapter-Official-Raspberry-Pi/dp/B01BJMRVQI/ref=sr_1_sc_1?ie=UTF8&qid=1456504802&sr=8-1-spell&keywords=wipi+wireless+official

is it compatible with OSMC?
Ragarding Power Supply you linked a 2A like the one I have, I expected you suggested me a 3A. Do you think it will work with Raspberry+IRC receiver+HDD+Dongle? What about Power HUB you mentioned above? Which one I should buy and How I have to connect everything?
Thanks

11

If you have the 2A PSU above, you should not have any problems. Is it an official Pi one?

The WiFi adapter you have linked to is the official Raspberry Pi adapter. It is based on BCM4330 and will work in OSMC out of the box.

12

Thanks You. You almost answered to all My question. What about power hub? Considerino My need above which one to Buy?

Le me be more specific. I Read everywhere that to run raspberry + hdd I need power hub + power supply of 3A. Above You said The officiata 2A is enough. This confuse me. What I have to Buy to power raspberry +hdd+dongle+irc receiver?

Ps
I do not have official 2A power supply. I have a normal 2A charter from Samsung.

13

Get a proper charger first. You should get away with one HDD on the USB with a proper 2A 5V PSU

14

All hdd I saw have only 1 usb port. No power supply entry (ie Wd portable elementi hdd)

15

The reso I do not want hdd with its own power supply is to reduce The numero of cables

16

I mean use a better Pi power supply, and you likely won’t need a PSU for your HDD. The Samsung charger is not good enough, it’s not really 5v 2A.

@sam_nazarko don’t forget he’s trying to power a wifi dongle too! I’m suspicious that even a 3A will support it all… This is why I recommended a powered hub.

18

I think 2A will do it. Regardless of this, OP still wants to get a better PSU. He could try the new PSU before determining if a hub is necessary

19

Ok I understand. Can you give me a link to power hub to buy and a brief description on how to Connect PSU, HDD and Raspberry?
I promise This is my last question.

Thanks You. Your support was quick and incredible.

Do not buy a power hub until you replace the PSU
